Howdahs are traditional wooden seats or platforms that are usually placed on the back of elephants or camels for transportation. However, there are several synonyms for the word howdah, which refer to similar types of seats or platforms used for animal transport. For example, a saddle may be used on a horse, mule, or donkey instead of a howdah, while a palanquin is a covered carriage that is carried by humans or animals. Other synonyms for howdahs include litter, pillion, and sedan chair. Each of these options offers a unique way to transport people or goods while incorporating the use of animals.
